ELEVATOR-HATCH GATE.

SPECIFICATION forming part ofLe tter s Patent No. 322,485, dated July21, 1885.

Application filed January 3, 1885. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES T. SoHULzE, a citizen of the United States,residing at Gincinnati, Ohio, have invented new and useful Improvementsin Elevator- Hatch Gates, of which the following is a specification.

My invention relates to safety-gates for elevator-hatchways, its objectbeing to provide a closure for such hatchways operated automatically bythe elevator mechanism, to prevent agcidents from leaving said openingsunguarde To this end my invention consists in a gate closing the flooropening or doorway of the elevator-hatchway, arranged to move verticallybetween guides, and provided with an elevating rack-bar combined withactuating idlers and an actuating rack-baron the elevator-cage, thewhole arranged to elevate the gate as the cage rises and depress thesame in the further movement of the cage in either direction; and itfurther consists in a construction of the apparatus enabling theelevator attendant to throw the same intoand out of operation at will.

Mechanism embodying my invention is illustrated in the accompanyingdrawings,in which Figure 1 is a general perspective elevation of theentire apparatus complete; Fig. 2, a detail View of aportion of thegate-rack, its boxing, and a gate,on a somewhat enlarged scale; Fig. 3,an elevation of the racks and idlers detached, showing more clearlytheir relation; and Fig. 4, an elevation and inverted plan,respectively, of the disconnecting devices for throwing the cage-rackout of its actuating position.

The parts designated herein are indicated by letters of reference on thedrawings.

Referring, now, to the drawings, A A designate two of the corner-postsof the elevatorhatchway, between which, as guides, the gate B has avertical movement; 0 and D D, idler spur-gears pivotally mounted uponstuds in the vertical path of a rack-bar, F, attached to theelevator-cage, and placed in engagement with the rack-bar H, attached tothe gate Bat one side, said rack-bar Hmoving in a boxing at the side ofor within the corner-post A.

P designates the platform, and E E the side stanchions of theelevator-cage.

The rack F is of alength corresponding with the height it is desired toelevate the gate B,

at the moment of such disengagement, engage the idler 0, thus keepingcontrol of thegate until it is again restored to'its position of rest,

as will more fully appear from the subsequent description of theoperation. The rack-bar H is twice the length of the rack-bar F, onehalfprojecting below the gate and'the other extending upward beside thegate, as shown.

A rubber cushion, K, at one or both sides of the gate, is provided toreceive the shock of the gate in descending.

In order to bring the engaging apparatus under control of the attendant,the rack-bar F is vertically pivoted to the frame of the cage, its pivotextending below the platform P, and there provided with aspur-pinion,W,engaging with a rack, R, moving horizontally in guides g g, and actuatedbya foot-lever, T, pivoted in the platform,as shown. The latter, beingfurnished with two foot-wings, t t, the

rack B may be moved in either direction at will, thereby throwing therack-bar F in or out of gear with the idlers G and D.

The operation of the devices is as follows: The elevator-cage being inthe position shown in Fig. 1, and rising, the rack-bar F engages firstthe idler D, whose rotation is transmitted through its mate D to therack H of the gate B, and the latter thereby elevated. When theelevator-platform is opposite the floor, its

rack is about to leave the idler D and engage the idler 0. Should thecage still rise, its rack engages the idler O and depresses the gate toits former position. Should it descend from the floor, its reverseaction upon the idlers D also depresses the gate to its normal position.

Should the gate B be an intermediate one, the rack F may be thrown asideby the foot-lever,

and the cage will then pass upward without moving the gate.

I claim as my invention, and desire to secure by Letters Patent of theUnited States- 1. The combination, in an elevator-hatchway, of the gateB with itsrack H, the elevator-cage with its rack F, and the idlers (land D D, substantially as set forth.

2. In an elevator-hatchway, in combination with the gate, its rack, andthe actuating idlers, a pivoted rack upon the cage, provided with means,substantially such as described, I In testimony whereof I have hereuntoset [0 for throwing the cage-rack into and out ofgear, my hand in thepresence of two subscribing as set forth. witnesses.

3. The combination, in an elevator-hatch- Way, of the vertically-movinggate, its attached CHARLES T. SOHULZE. rack, the cage-rack, the idlersarranged in the path of the cage-rack, and the foot mechanism Witnesses:for throwing the cage-rack out of gear, sub- L. M. HOSEA,
